The Mysterious Billionaire and His Substitute Bride (Ethan and Janet) novel Chapter 564

"It's a very dangerous and rare kind of poison that can cause heart palpitation, which later leads to a sudden cardiac arrest," Frank answered seriously. "It takes time for it to take effect, with an incubation period of around one or two days once it enters the human body."

Ethan's expression darkened. Frank didn't know what was on his mind because Ethan kept silent.

"Who owns the blood?" Frank asked again. "If it's someone close to you, you'd better have a few more tests done. If the poison is still in their system, their life may still be in danger."

"Keep the sample and the test results safe," Ethan said in a dangerously low voice.

Frank didn't ask any more questions. Judging from Ethan's slightly trembling voice, he realized the gravity of the situation and fell silent. He hadn't seen Ethan like this in a long time.

Ethan hung up the phone without another word.

Just then, he heard footsteps coming from the stairs. Janet came downstairs wrapped in a blanket.

Just now, she saw how Ethan's expression changed after receiving the phone call. She was a little worried, so she came out to check on him.

After hanging up, Ethan stood there motionlessly, his eyes as dark as night. Janet looked at him worriedly, not knowing what was going on in his mind.
